IMPROVEMENT IN HORSE-RAKES.

TO ALL ll/'HOM IT MAY CON CERN Be it kncwnthat I, ELLIS LUTHER, of WestTroy, in the county of Albany, and State of New York, have inventedcertain new und useful Improvements in Horse HayRakcs; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference beingr hereby had `to the accompanying drawings,which form and make a. part ofthis speciiication.

Like letters represent and refer t like or correspondingparts.

Figure 1 is -aperspective view of a horserake containing my inventionand improvements.

Figure 2 is a transverse section of said rake in its usual position whengathering the hay.

Figure 3 is another section of the same, in the'act of making arevolution; and

lFigure 4 is a plan of the said rake, as seen from the top. My inventionrelates to that species of horse-rake which is fitted withwheels andadrivers seat. Here- Vtofore this kind of rake has been operated by alever, attached to a beam above the rake-head, and crossing thesame atright angles, to one end of which bea-m is suspended a cross-har, and tothe other a pair of diverging spring-bars. rlhe cross-bar presses on therear teeth of the rake, and prevents a revolution before the propertime, while tbespring-lars pressthe front teeth into the ground, when itis desired to revolve the rake. There are two great defects ln thismode'of operation: Unless the lever or handle is at once drawn back, atthe time ofthe revolution,the spring-bars are pressed into the groundand broken ofi', and this is almost sure to be done by inexperienceddrivers.-. Again, the c ross-bar, lat the time of the revolution, is aptto catch' a lock of hay, which either entanglcs the teeth or is woundaround the rakehead, thus compelling the driver to frequentlyaget downto unclog therake. Y

My invention is intended to obviate these defects, 'and dispenses withthe spring and cross-bars, employing in their place a device for liftingthe rear part of the rake, so that the front teeth will catch in theground and cause a revolution, which device is constructed and operatedas follows A is the shaft vor aide of the rake; B, the beams, reachingfrom the axle to the V head ofthe rake; H, the shafts, between which thehorse is fastened; E isa frame, resting upon the axle Aand thecross-piece D; W is n rock-shaft, supported ou uprights, placed upon theframe E, and to which is attached, at one, end, the

compound lever I K V, and at the middle, the lever J. The arm M is' alsorigidly attached to said rock-shaft W.

G is e. block, in the rear of the middle of the rak'e, and attached tothe rake'head by a metal band, at' C, which ts loosely, and permits therake to revolve within it. P is a. sort'of'ci'adle, attached to theupper surface of thej'blocli G, by screws through the bottom, 'and withthe two sides connected by bolts or pivots at e and' jl a and a are tivohooked levers, inserted in the frontend rear ofthe middle oftherekejhcad. I) is a dog, which rests on thel upper part ofthe rear levera, when the rake is in the usual position. o is a hook, which engageswith the'lever a, inrevolving the rake. Both 6 and c are attached to thepivot e. d is a spring, which causes' the hook c to catch the end of thelever a. N'is an arm, attached' at one end tothe rear part ofthe cradle4P,- and at the otherend to the lever J. O isla chain, connecting the armM with the frontof'said cradle P, by means of the pivotf, and used forlifting the rake from the ground, as hereinafter described. T is a cord,extending from theaxle (t to the top ofthe dog- It will be seen thatwhen the rake is drawn Lalong in a horizontal position for the purposeof gathering the hay, the dog rests upon the hooked lever a, andkeeps-.the rake from revolving, even if the teeth should accidentallycatchin the ground. y

When the driver desires to revolve the rake, he pulls the lever Jtowards lim, thus raising the opposite end of the lever. The arm N isthen raised, and with it the rear of` the cradle P. Y The hook c engageswith lthe hooked lever a, and raises the r'enr part of the rake,` whilethe cord T disengages the dog b from the said lever rz, 4and permitsitto pass as lthe ruhe revolves. By means of this half revolution thefront lever a strikes the end ofthe hook c', and presses it back enoughto pass the spring d, keeping it in proper place. The dog 6 then fallsback to place, and the position is the same as before. When the driverdesires `to raise the whole rake from the ground, to avoid obstacles, orfor other reasons, he plis towards him the handle I of the compoundlever I KV. This causes Lthe rock-shaft W to perform a quarterrevolution, which raises the arm M to a horizontal position, and bymeans of the chain o raises the front part of the cred-le P, and withit, the whole rake from the ground. A i

Havingthus described the nature of my said invention and improvements,Whatl clziim, and desire'to secure by Letters Patent ofthe UnitedStates, isf- 1. The block Grond cradle P, in combination with each otherand withthehead of the rake, substantiallyas hereinbefore described andset forth.

2. I also claim the combination of the dog b and the hook c with thecradle P, snhstantially as hereiubefore described and set forth. Y l

3. I also claim the combinurtion of the spring d with the hook c,substantiallyns herein specified and set forth.

4. Iclaim the combination Aof the arm N with the cradle P and the leverJ, substantially as herein specified and set forth. l

'5. I claim the combination ,of the cord T with the dog ZJ and axle A,substantially ns herein specified and described.

6. I claimthe lever J, the nrxn N, the crade P, the hooi: c, the hookedlever a, and the spring d, all arranged and combined substantially asand for the purposes iieieinbefore described and set-forth. A'

7. Iclai'm the combination of the cradle l with the chain o,substantially as hereinbefore stneal undiset foi-th.

i In testimony whereof, I have hereunto set my hand, this 8th day oiOctober, A. 186i'.
